FUEL-BURNING sYs'rEM.

Application filed Ap ril li8, 1925; Serial No. 24,080.

This invention relates to a liquid fuel ing the reservoir, suction and pressure pump, and atomizer and airlinescommuni eating with said fuel line. i y

The invention has for-one of its objects to provide in aliquidfuel burning system an air line in communication with the fuel line and including valve means for regulating the volume of 'airtothe fuel line, whereby to control the consumption of fueland the siphonic-action in the system. v

The invention has for a further object the provision of means in the fuel line to intercept the flow of the fuel therein by the admission of air, resulting in breaking up the fuel flow and causing the same to be conveyed to the burner under slight pressure, which is not unlike in'purpose and object the subject matter includedin an applic'a tion filled by menu or about February 2, 1925 for improvements in a fuel burning system bearing Serial No.6,2 l8. i i

The invention has fora still furtherobject to provide in a liquidyfuel burning system a. suction. and pressure pump, an air pump and an atomizer; the suction and pressure fuel pump being connected by a supply line with thesource of supply and to anair linev having a controlling means thereing isaid suction and pressure pump and said air pump being connected with the atomizer through fuel and air supply lines,a connection being made between the latter two lines,

the fuel line of which at the point of introduction of air thereinbeing provided with means intercepting the fuel and air, to break up the how of fueland to apply a pressure of air thereto, which minimizes the consumption of fuel and presents it to the atomizer in a more perfect state. i

The inventionsfurther comprehends a liquid fuel burning system designedforheating" purposes in thehomeor elsewhere, com prising a fuel reservoir located preferably underground and 'at'a distance from the burner, although it is to be understood that it may be located iii'the basement of a dwelling or elsewhere, providedwith a fuel supply line leading from the fuel reservoir to a suction and pressure pump located ,pref-' erably within the building or dwelling, the

fuelQline being intercepted at some inter mediate point preferably within the build ing or dwelling by an air line having a controlmeans therein; the fuel line extending from the suction and pressure. pump and communicating with a coupling into and through which the liquid fuel is caused to pass and into a fuel line terminating in an M atomizer located preferably withinthe heater or furnace an air pressure pump having a inore'or less direct communication with" the atomizer by means of an air line, and

intercepted in its length by a communicating air, pipe having connection to said coupling through which air is "caused to pass and in-' termingle with the fuel on its passage to the atomizer. I i i That the invention may be more fully understood, reference ishad to the accompanyingdrawings, illustrating a preferred embodiment of the invention and forming part of this descriptiomin which:

In Figure 1 a fuel reservoir or container 1 is shown pref-erablylocated underground and outside of a building or dwelling ,2. Connected near the top of the reservoir 1 an air vent 3 is provided for the ingress and egress of air to the outside atmosphere.

Depending within the reservoir 1 to within a short distance fromthe bottom-thereofis a fuel supply pipe or'line 4: whichis'con nected to the top of the reservolrgandby means of an L 5 the pipe or line 4 takes of any desired length, however, it is desirable'to have said line or pipe terminate at a point near the furnace or heater to be within easy reach of an attendant, and at or.near the terminus of said line or pipe, the same is provided with'a controlling and regulating valve 10, the purpose of which will be further explained.

Leaving the fuel pump 8 on the pressure side thereof, the fuel line or pipe 4 takes preferably a horizontal direction to an L 11 where it is directed upwardly and is attached. to the coupling 12, to be more fully described. The fuel line or pipe 4 leaves connections is attached to the atomizer the discharge end of the coupling 12 and by means of the Ls 13 and 14 takes prefera 1y a horizontal direction and by suitable which is preferably located within the furnace or heater 16, shown in dotted lines in Figures 1 and 2.

A suitable source of power, preferably shown'by means of an electric motor 17 ineluding a driving *belt 18suitably'connected to the air pressure pump or blower 19, see Figure 1, is 'usedto operate the air pump 19 and fuel pump 8. Within the housing or casing 20 of the air pump 19 are suitably mounted'air vanes '21 on the driving shaft 22,"see Figure 3, and which supply a pressure of air from the pipe opening 23 out through the discharge opening 24 into the air line or pipe 25, to be more fully described. Suitably mounted within the supply pipe opening 23 of the air pump or blower 19 is an adjustable valve 26 provided with a hand lever 27 for controlling the ingress of air into the air pump'or blower 19, as desired. The suction and'pressure fuel pump 8 derives 'itsoperation through the extension of the driving shaft 2201 the air pump or blower 19 upon which is provided a toothed gear 28 which acts in co-operation with another similar toothed gear -29,'which when in operation creates a sufiicient suction in-the fuel line 4 as to cause fuel to be supplied from the reservoir 1 to the jfuel'pum'p 8, and further to create a sufficient pressure as to cause the liquid fuel to be forced through the fuel line or pipe and pipeconnections to the atomizer 15, as will e understood. Connected to the discharge opening ofthe airpressure pump or blower 19 is antairpipe orline 25, previously referred to, which is connected directly to the atomizer, 15, see

secured to one end and on its underneath side is secured the fuel line or pipe 4,. the fuel pipe orline 4 being also secured to the discharge end of the couplin 12oppositethe air pipe or line 30. Provided in the interior of the coupling 12 and in the plane of the air pipe or line 30 and discharge fuclpipe or line 4 is a short nozzle 31 extending horizontally of the coupling and slightly in advance of the fuel pipe or line 4 which has connection on the underneath side thereof. It will be understood that liquid fuel upon entering the coupling 12 throu 'h theopening on the underside thereof will of necessity be caused to enter the fuel line or pipe 4 leading therefrom due to the pressure of air from the air pipe or line '30 assi'ng throu'gh the nozzle 31 which internnngles with the liquid fuel and also tends to pick up or aid the same through the *fuel line or pipe 4 to the atomizer 15. The liquid fuel burning systems now in use which'employ a sue tion and pressure ump to supply the fuel burner with liquid fuel have experienced more or less difficulty in obtaining an even flow of fuel through the fuel lines to the point of consumption. The most common complaint in this regard has been that the liquid fuel would flow in spurts through the fuel lines causing the burner to burn unevenly and at times even vbe'ext'inguished, causing a fire hazard. The coupling 12 is designed to remedy this'contlition and it will be understood, 'thattheliquid fuel gaining entrance to the coupling *12 would :be gurgling and'spurting past the n0zzle31 in uneven amounts, however, a pressure of mil? supplied to the coupling 12 by means of the no air line 30 would be discharged within the coupling 12 through the nozzle 31- and be intermingled with the liquid fuel with the result that the liquid fuel is supplied to the atomizer 15 in an even stream and under a slight pressure due to the air pressure intermingled with the fuel.

In Figure5'the atomizer 15 is shown having an air supply pipe or line 25 communicating rearwardly of the'same with an up standing annular air chamber or recess-32 which has connection with a diagonally dis posed recess orchamber 33 communicating with the front face of the atomizer'preferably near the center thereof. The fuel line or pipe 4 is connected to the atomizer 15 preferably centrally of the same communicating with a-short horizontal fuel opening or channel 34 which terminates in the front face of the atomizer and preferably adja- 13o meansam line'eonnect'ingthe'air pressure means with. said burner and .m communication' with; said fuel line: on the pressure side v of'said pressure means, and an ejector G1 the: fuel, line latithejuncture of said last men tiOned: air line. with said fuel line;
